Cache-aided rollback error recovery (CARER) algorithm for shared-memory multiprocessor systems

Three cache-aided error-recovery algorithms for use in shared-memory multiprocessor systems are presented. They rely on hardware and specially designed cache memory for all their soft error management operations and can be easily incorporated into existing cache-coherence protocols. An example illustrating their use in a multiprocessor system employing Dragon as its cache-coherence protocol is given, and the results of a tradeoff analysis are presented.<>
